At the heart of cognitive science lie two problems: the nature of our knowledge and how it emerges. For many centuries, these issues were the province of philosophers only. Nativists such as René Descartes argued that much of our knowledge was innate, driven by the character of the human mind and only indirectly by the nature of the particular events we might experience. By contrast, empiricists such as John Locke argued that very little of our knowledge (...) was innate; rather, he argued that knowledge was acquired through a lengthy process of learning in which the putative primitive elements of thought – the sensations – came to be associated with each other, yielding higher‐level concepts. While no longer the sole province of philosophy, the nativist and empiricist frameworks have come to organize some of the most important issues in cognitive science today: How can we characterize human knowledge? How does it emerge? What are the relative contributions of innate structure and learning through experience? (shrink)

It is sometimes argued that if PDP networks can be trained to make correct judgements of grammaticality we have an existence proof that there is enough information in the stimulus to permit learning grammar by inductive means alone. This seems inconsistent superficially with Gold's theorem and at a deeper level with the fact that networks are designed on the basis of assumptions about the domain of the function to be learned. To clarify the issue I consider what we should learn (...) from Gold's theorem, then go on to inquire into what it means to say that knowledge is domain specific. I first try sharpening the intuitive notion of domain specific knowledge by reviewing the alleged difference between processing limitations due to shortage of resources vs shortages of knowledge. After rejecting different formulations of this idea, I suggest that a model is language specific if it transparently refer to entities and facts about language as opposed to entities and facts of more general mathematical domains. This is a useful but not necessary condition. I then suggest that a theory is domain specific if it belongs to a model family which is attuned in a law-like way to domain regularities. This leads to a comparison of PDP and parameter setting models of language learning. I conclude with a novel version of the poverty of stimulus argument. (shrink)

In Posterior Analytics 2.19, Aristotle argues that we cannot have innate knowledge of first principles because if we did we would have the most precise items of knowledge without noticing, which is impossible. To understand Aristotle’s argument we need to understand why he thinks we cannot possess these items of knowledge without noticing. In this paper, I present three different answers to this question and three different readings of his argument corresponding to them. The first two (...) readings focus on the fact that we do not use the knowledge we allegedly possess innately. However, I argue that these readings fail to produce convincing arguments. I then offer a third reading, which focuses on the fact that we do not notice the knowledge we allegedly possess innately when we use it for the first time. I argue that this reading produces a more convincing argument than either of the first two. (shrink)

The theological aspect of the dispute between the modern philosopher René Descartes, and the Calvinist theologian, Gisbertus Voetius, remains a chapter insufficiently explored in Cartesian studies. This paper highlights a set of objections on natural theology addressed by Descartes and Voetius to each other. It shows and expands the common ground Descartes and Voetius held within natural theology. It argues that their contrasting views revolved mainly around the limits of natural theology. For Voetius, natural theology is extrinsically limited by the (...) revealed God, the external principle of faith. For Descartes, metaphysics or natural theology is intrinsically limited by the incomprehensible idea of the Infinite. (shrink)

This article starts from the assumption that there are various innate contributions to our view of the world and explores the epistemological implications that follow from this. Specifically, it explores the idea that if certain components of our worldview have an evolutionary origin, this implies that these aspects accurately depict the world. The simple version of the argument for this conclusion is that if an aspect of mind is innate, it must be useful, and the most parsimonious explanation (...) for its usefulness is that it accurately depicts the world. There are a number of important criticisms of this argument. These include the idea that evolutionary justifications are circular, that evolved mental content and principles are not necessarily accurate, and that, if the argument is taken seriously, it has some highly dubious consequences. These criticisms necessitate various qualifications to the initial argument. Nonetheless, it is argued that, in some cases, important conclusions can be drawn about the world from an analysis of evolved contributions to our view of the world. An evolutionary approach cannot provide an ultimate justification for any belief; however, in certain circumstances, it supports the conclusion that a given belief is a reasonable first approximation. To the extent that innate content and principles pertain to topics in metaphysics, they can be viewed as a naturalistic source of metaphysical knowledge. (shrink)

Malcolm Jones; Innate Powers, Concepts and Knowledge: a critique of D. W. Hamlyn's account of concept possession, Journal of Philosophy of Education, Volume 15.

In his "The Empiricism of Avicenna," Dimitri Gutas interprets Avicenna as an empiricist.1 He analyzes Avicennian 'principles of syllogism' and claims that none of them are a priori. Moreover, regarding awwalīyāt and fiṭrīyāt—which are two groups of such principles—Gutas suggests that "[i]t appears that both kinds of propositions would be analytic, in Kantian terms. As for Locke, they would be what he called 'trifling.'"2 In my first comment in this issue, I disagreed with this view and argued that these two (...) groups of propositions are a priori in the Kantian sense. Assenting to their truth is internal to the intellect and independent of empirical information. I also argued that at least some fiṭrīyāt are synthetic... (shrink)

In historical claims for nativism, mathematics is a paradigmatic example of innate knowledge. Claims by contemporary developmental psychologists of elementary mathematical skills in human infants are a legacy of this. However, the connection between these skills and more formal mathematical concepts and methods remains unclear. This paper assesses the current debates surrounding nativism and mathematical knowledge by teasing them apart into two distinct claims. First, in what way does the experimental evidence from infants, nonhuman animals and neuropsychology (...) support the nativist hypothesis? Second, granting that infants have some elementary mathematical skills, does this mean that such skills play an important role in the development of mathematical knowledge? (shrink)

This paper provides a rigorous defense of innate true belief in the Meno, to my knowledge, the first of its kind. While several commentators have proposed innate true belief in the past, the position has never been defended or explained in detail. Instead, the most thorough discussions of Plato’s innatism have opted for different innate objects. I defend my proposal against these recent alternatives by showing that the passages often thought to imply innate knowledge (...) can be read in other ways. I then argue that they should be so read, because of an “awareness condition” Plato had on knowledge at the time. (shrink)

Although linguistic nativism has received the bulk of attention in contemporary innateness debates, moral nativism has perhaps an even deeper ancestry. If linguistic nativism is Cartesian, moral nativism is Platonic. Moral nativism has taken a backseat to linguistic nativism in contemporary discussions largely because Chomsky made a case for linguistic nativism characterized by unprecedented rigor. Hence it is not surprising that recent attempts to revive the thesis that we have innate moral knowledge have drawn on Chomsky’s framework. I’ll (...) argue, however, that the recent attempts to use Chomsky-style arguments in support of innate moral knowledge are uniformly unconvincing. The central argument in the Chomskian arsenal, of course, is the Poverty of the Stimulus (POS) argument. In section 1, I will set out the basic form of the POS argument and the conclusions about domain specificity and innate propositional knowledge that are supposed to follow. In section 2, I’ll distinguish 3 hypotheses about innateness and morality: rule nativism, moral principle nativism, and moral judgment nativism. In sections 3-5 I’ll then consider each of these hypotheses in turn. I’ll argue that while there is some reason to favor rule nativism, the arguments that moral principles and moral judgment derive from innate moral knowledge don’t work. The capacity for moral judgment is better explained by appeal to innate affective systems rather than innate moral knowledge. In the final section, I’ll suggest that the role of such affective mechanisms in structuring the mind complicates the standard picture about poverty of the stimulus arguments and nativism. For the affective mechanisms that influence cognitive structures can make contributions that are neither domain general nor domain specific. (shrink)

The commentators raised issues relevant to all three important theses of The Origin of Concepts (henceforth TOOC). Some questioned the very existence of innate representational primitives, and others questioned my claims about their richness and whether they should be thought of as concepts. Some questioned the existence of conceptual discontinuity in the course of knowledge acquisition and others argued that discontinuity is much more common than was portrayed in TOOC. Some raised issues with my characterization of Quinian bootstrapping, (...) and others questioned the dual factor theory of concepts motivated by my picture of conceptual development. (shrink)

The concepts of the innateness, universality, species-specificity, and autonomy of the human language capacity have had an extreme impact on the psycholinguistic debate for over thirty years. These concepts are evaluated from several neurobiological perspectives, with an emphasis on the emergence of language and its decay due to brain lesion and progressive brain disease.Evidence of perceptuomotor homologies and preadaptations for human language in nonhuman primates suggests a gradual emergence of language during hominid evolution. Regarding ontogeny, the innate component of (...) language capacity is likely to be polygenic and shared with other developmental domains. Dissociations between verbal and nonverbal development are probably rooted in the perceptuomotor specializations of neural substrates rather than the autonomy of a grammar module. Aphasiologicaldata often assumed to suggest modular linguistic subsystems can be accounted for in terms of a neurofunctional model incorporating perceptuomotor-based regional specializationsand distributivity of representations. Thus, dissociations between grammatical functors and content words are due to different conditions of acquisition and resulting differences in neural representation. Human brains are characterized by multifactorial interindividual variability, and strict universality of functional organization is biologically unrealistic.A theoretical alternative is proposed according to which (1) linguistic specialization of brain areas is due to epigenetic and probabilistic maturational events, not to genetic ”hard-wiring,” and (2) linguistic knowledge is neurally represented in distributed cell assemblies whose topography reflects the perceptuomotor modalities involved in the acquisition and use of a given item of knowledge.

Contemporary debates in epistemology devote much attention to the nature of knowledge, but neglect the question of its sources. This book focuses on the latter, especially on the question of innateness. Carruthers' aim is to transform and reinvigorate contemporary empiricism, while also providing an introduction to a range of issues in the theory of knowledge. He gives a lively presentation and assessment of the claims of classical empiricism, particularly its denial of substantive a priori knowledge and of (...) innate knowledge. He argues that we would be right to reject the substantive a priori but not innateness, and then presents a novel account of the main motivation behind empiricism, which leaves contemporary empiricists free to accept innate knowledge and concepts. Carruthers closes with a discussion of scepticism, arguing that acceptance of innate concepts may lead to a decisive resolution of the problem in favor of realism. (shrink)

Empiricism, the philosophical theory that all our ideas and knowledge are derived from experience, has in recent years been the target of radical and persuasive objections. In the seventeenth century, and for long after, rationalism seemed the only alternative to empiricism, but, like Kant, many contemporary philosophers have been convinced that empiricism and rationalism are equally unacceptable, and that both positions, and the conflict between them, are the result of trying to answer confused, misleading, and perhaps senseless questions. Of (...) all the traditional theories in particular, none, I suppose, has looked to modern philosophers less capable of being revived than the rationalist doctrine of innate ideas: the doctrine that some at least of our ideas and knowledge of things are not derived from outside the mind, through experience, but are present from birth in the mind itself and thus represent the mind's own contribution to our understanding of reality. What Strawson has called ‘those old and picturesque debates regarding the origin of our ideas’ seemed to have become museum pieces, charming, as antiques can be, but with little relevance to current issues. These complacent attitudes, if that is what they are, have been rudely disturbed by Chomsky and his colleagues. Chomsky has suggested ‘that contemporary research supports a theory of psychological a priori principles that bears a striking resemblance to the classical doctrine of innate ideas’. In the prevailing situation, the novelty of this suggestion is twofold. It is not only that the theory of innate ideas may be true after all, but also that the support alleged for the ancient doctrine has a distinctively modern look. The research that Chomsky claims supports the doctrine is research in the empirical science of linguistics. The implication is that empiricism is refutable empirically, and more generally that a philosophical dispute such as the dispute between empiricism and rationalism, once it is made clear, can be settled by science.

An argument that nativism is true and important but mysterious, examining the particular case of ideas of sensible qualities. In this book, Colin McGinn presents a concise, clear, and compelling argument that the origins of knowledge are innate—that nativism, not empiricism, is correct in its theory of how concepts are acquired. McGinn considers the particular case of sensible qualities—ideas of color, shape, taste, and so on. He argues that these, which he once regarded as the strongest case for (...) the empiricist position, are in fact not well explained by the empiricist account that they derive from interactions with external objects. Rather, he contends, ideas of sensible qualities offer the strongest case for the nativist position—that a large range of our knowledge is inborn, not acquired through the senses. Yet, McGinn cautions, how this can be is deeply problematic; we have no good theories about how innate knowledge is possible. Innate knowledge is a mystery, though a fact. McGinn describes the traditional debate between empiricism and nativism; offers an array of arguments against empiricism; constructs an argument in favor of nativism; and considers the philosophical consequences of adopting the nativist position, discussing perception, the mind–body problem, the unconscious, metaphysics, and epistemology.

Empiricism is a philosophical school that focuses knowledge only on the senses. One of the characters is John Locke. In Locke's view, he emphasized that knowledge comes from observations we make of our own surroundings with a tool called John Locke sensing, which he considers this as a white sheet of paper and rejects innate ideas. Locke views reason as a passive shelter receiving the results of the senses. Locke considered what he called knowledge to be (...) a composite of ideas derived from sensory experience. Locke generalizes to knowledge. The research aims to answer the problems that arise from Locke's view by criticizing the theory of tabularasa based on huduri science by using huduri according to Tabataba'i. as for this research using qualitative methods and literature. As for analyzing the data using a theory demonstration criticism approach. From the research that has been done by the author, it shows that huduri science is the capital for every knowledge, even for knowledge that is preceded by the senses. Because in essence knowledge is something immaterial, as for what enters the subject who knows is something immaterial too, even though the object is bound by matter. This is what is called the presence of something immaterial in the immaterial soul. (shrink)

Recent years have seen a renewal of the perennial debate concerning innate ideas: Noam Chomsky has argued that much of our knowledge of natural languages is innate; Jerry Fodor has defended the innateness of most concepts. ;Part One concerns the historical controversy over nativism. On the interpretation there developed, nativists have defended two distinct theses. One, based on arguments from the poverty of the stimulus, is a psychological theory postulating special-purpose learning mechanisms. The other, deriving from arguments (...) entailing that learning from experience is impossible, is the meta-psychological view that we can hope for no real explanation of how learning occurs. ;In Part Two, the views of contemporary nativists are discussed against this background. Fodor's claim that our concepts are 'triggered' rather than 'learned' provides no account of concept-acquisition. Instead, it expresses his view that concept-acquisition resists any psychological explanation. But while 'brute-causal' interaction with the world may be necessary to the fixation of reference--and hence to the attainment of concepts--it is insufficient. Mind-world interaction is 'cognitively mediated' and it is in explaining the nature of this mediation that psychology will play a role. ;Chomsky holds that we have a special-purpose faculty for learning language. His 'a posteriori' arguments from the poverty of the stimulus, being based on unsubstantiated empirical claims about the pld and the course of learning, are rejected. Another 'a priori' argument exists, however, involving only the general observation that since the pld contain little information about what is not a sentence, a special mechanism is required to prevent overgeneration. But negative data are lacking in every learning domain. So since it is implausible that all learning requires special faculties, there must be a general-purpose strategy that can skirt the 'negative evidence' problem. Whether it is used for language-learning remains moot. But what really motivates the Chomskian is his awe at what children achieve, namely, 'cognizance' of a grammar. Grammars prove, however, to be 'psychologically real' in such a weak sense that the phenomena of language mastery provides little grist to the nativist's mill. (shrink)

This chapter contains sections titled: Three Arguments.

The concept of innateness is central to Descartes's epistemology; the Meditations display a new, non-Aristotelian method of acquiring knowledge by attending properly to our innate ideas. Yet understanding Descartes's conception of innate ideas is not an easy task, and some commentators have concluded that Descartes held several distinct and unrelated conceptions of innateness. In Descartes on Innate Ideas, Deborah Boyle argues that Descartes's remarks on innate ideas in fact form a unified account. Addressing the further (...) question of how Descartes thinks innate ideas are known, the author shows that, for Descartes, thinkers have implicit knowledge of their innate ideas. Thus she shows that the actual perception of these innate ideas is, for Descartes, a matter of making them explicit, turning the intellect away from sense-perceptions and toward pure thought. The author also provides a new interpretation of the Cartesian "natural light," an important mental faculty in Descartes's epistemology. (shrink)

Despite a vast philosophical literature on the epistemology of mathematics and much speculation about how, in principle, knowledge of this domain is possible, little attention has been paid to the psychological findings and theories concerning the acquisition, comprehension and use of mathematical knowledge. This contrasts sharply with recent philosophical work on language where comparable issues and problems arise. One topic that is the center of debate in the study of mathematical cognition is the question of innateness. This paper (...) critically examines the controversy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Leibniz on Innate Ideas and the Early Reactions to the Publication of the Nouveaux Essais (1765)* GIORGIO TONELLI LIzmNIz' Nouve~ Essais,written in 1703-1705 (citedhereafter as NE), were posthumously published by Raspe x in 1765, at the beginning of a Leibniz revivalwhich was alsomarked by thelargeDutens editionof 1768. As the greatupheaval in Kant's thought took place in 1769, and as thisupheaval had as one of itsmain characteristicsthe rejection of (...) sensibility as the sole source of knowledge,2 it is easy to infer that Kant's reading of the NE may have been one of the elements prompting him to adopt his new solution. It is not the ambition of this paper to answer that difficult question: rather it is an attempt towards clearing the ground for an answer to it, by inquiring into the early reactions of philosophical circles, especially German, to the appearance of the NE. To what extent was the significance of the particular doctrines expounded in the NE noticed? To what extent did contemporary philosophers realize that these were to profoundly modify the picture of Leibniz' psychological tenets? And, therefore, to what extent could Kant have been stimulated by a widespread reaction to pay special attention to the peeu!ia~lies of that work7 In conformity with this purpose, I shall focus my research on the question o/the origin of knowledge. As it is my task to reconstruct a general philosophical atmosphere, I will not confine my research to philosophic reactions prior to 1769, but will also take into consideration some attitudes of the following decade. As frequently happens in the history of ideas, the impact of a certain event may be noticed almost immediately after its occurrence, but the documentation of its effects may be available only after a certain delay. But they are nevertheless indicative of that prior impact. Before starting this enquiry, I shall: (1) point out the difference between the doctrine in question as it is expounded in the NE and as it appeared in the previously published works of Leibniz; (2) examine the interpretations of Leibniz' psychology prior to 1765, especially as represented in the version which was accepted by Wolff and incorporated into his system. * I want to expressmy gratitude to my friend Dr. Heinrieh Schepers,Director of the LeibnizStelle of Miinster University, for severalreferences and suggestions,and for his sympathy with the subjectof this paper. 1 Oeuvres philosophique$ latines et franfaises du feu Mr. de Leibniz tir~es de ses Manuscrits qui #e conservent dans la Biblioth~que royale ~ Hanovre et publi~es par M.

It is an obvious principle in Leibniz' metaphysics that all knowledge stems from the interior of the soul, or monad: from this point of view, it may correctly be stated that for Leibniz all knowledge is innate. It is equally obvious in our day that Leibniz held that there is a basic distinction between the way we know necesstwy and universal truths, emerging from the soul's intellect, and the way we know contingent and particular truths, emerging from the soul's sensibility. Therefore, from a psychological and exoteric point of view (as in the NE) the first kind of truths may be called innate (par excellence), while the second may be called acquired. As it happened, the works of Leibniz published prior to 1765 almost exclusively represented the general metaphysical point of view, and this led to a fatal distortion of his thought by his followers. The interpretations of Leibniz were from the very beginningm and still are in our day---profoundly influenced by the fact that many of Leibniz' works were not published in his lifetime, but appeared (and still shall appear) posthumously during more than two centuries. Consequently the distinction between the origin of necessary and the origin of contingent truths was generally overlooked. This is clearly explained by an examination of Leibniz' worksa which were published before his death (1716) and shortly thereafter. One of the most influential... (shrink)

A large campaign has sought to destigmatize psychiatric disorders by disseminating the view that they are in fact brain disorders. But when psychiatric disorders are associated with neurobiological correlates, laypeople's attitudes toward patients are harsher, and the prognoses seem poorer. Here, we ask whether these misconceptions could result from the essentialist presumption that brain disorders are innate. To this end, we invited laypeople to reason about psychiatric disorders that are diagnosed by either a brain or a behavioral test that (...) were strictly matched for their informative value. Participants viewed disorders as more likely to be innate and immutable when the diagnosis was supported by a brain test as compared to a behavioral test. These results show for the first time that people spontaneously essentialize psychiatric conditions that are linked to the brain, even when the brain probe offers no additional diagnostic or genetic information. This bias suggests that people consider the biological essence of living things as materially embodied. (shrink)

The Credit Theory of Knowledge (CTK)—as expressed by such figures as John Greco, Wayne Riggs, and Ernest Sosa—holds that knowing that p implies deserving epistemic credit for truly believing that p . Opponents have presented three sorts of counterexamples to CTK: S might know that p without deserving credit in cases of (1) innate knowledge (Lackey, Kvanvig); (2) testimonial knowledge (Lackey); or (3) perceptual knowledge (Pritchard). The arguments of Lackey, Kvanvig and Pritchard, however, are effective (...) only in so far as one is willing to accept a set of controversial background assumptions (for instance, that innate knowledge exists or that doxastic voluntarism is wrong). In this paper I mount a fourth argument against CTK, that doesn’t rest on any such controversial premise, and therefore should convince a much wider audience. In particular, I show that in cases of extended cognition (very broadly conceived), the most salient feature explaining S ’s believing the truth regarding p may well be external to S , that is, it might be a feature of S ’s (non-human, artifactual) environment. If so, the cognitive achievement of knowing that p is not (or only marginally) creditable to S , and hence, CTK is false. (shrink)

This article critically assesses the empirical research that leads Quine, in his posthumously published work, to abandon his empiricist principle that humans do not have any innate concepts, or knowledge. It is the same empirical research that Penelope Maddy capitalizes on to develop her own contributions to naturalized epistemology, and it has been pioneered by developmental psychologist Elisabeth Spelke. Spelke employs the method of habituation and preferential looking to argue that human infants have innate concepts, and that (...) they have some knowledge about what can and cannot happen to physical objects. Taking into account empirical studies as well as methodological considerations, this article examines whether this research can support these strong philosophical conclusions drawn from it, finding that it likely cannot provide such support.
